Abstract

Sodium N-[(trimethylamineboryl)-carbonyl]-L-phenylalanine 2 and {N-[(trimethylamineboryl)-carbonyl]-L-phenylalanyl- carbxylato}-bis-{N-[(trimethylaminebryl)-carbonyl]-L-phenylalanine} dicopper (II) 3 were successfully synthesized. The agents blocked L(1210) leukemic cell DNA and RNA syntheses by inhibiting multiple enzyme activities for nucleic acid synthesis, e.g. PRPP amido transferase, IMP dehydrogenase, DNA polymerase alpha, thymidine kinase, and TMP kinase. The copper (II) complex 3 demonstrated improved ability to inhibit L(1210) partially purified DNA topoisomerase II compared to the parent compound while the sodium salt was inactive at 100 muM.
